Imperial County, CA Building Setbacks & Zoning: Structure Height Limits (2026)

Imperial County does not set one countywide maximum building height; instead, height limits are established for each zoning district in the Land Use Ordinance, Title 9, Division 5 (Zoning Areas Established), so the allowed height depends on whether a parcel is in a residential (R), agricultural (A), commercial or industrial zone. Each zone chapter (for example R-1, Section 90502 and following) carries its own development standards, and the applicable height maximum and any story limit are read from that zone's standards. Because the exact figure varies by district and the County administers it parcel-by-parcel, the reliable way to confirm a height limit is to identify the parcel's zoning on the County zone maps and check the corresponding chapter, or ask Planning & Development Services directly. For structures that are fences or walls rather than buildings, the ordinance is specific: under Title 9, Division 4, Chapter 3, a masonry fence or wall over four (4) feet in height must be built to the specifications of the adopted California Building Code and designed by a California-licensed civil engineer or architect, while front-yard fencing in residential zones is capped at 30 inches (obscure) or 48 inches (translucent). Building height is also affected by the California Building Code the County has adopted, which governs construction type, occupancy and structural limits. Owners planning a tall building, second story or accessory structure should verify the zone-specific height maximum and any conditional-use requirements before designing, since exceeding the zone limit typically requires a variance.
